Building and Evaluating Advanced RAG Applications
Reviewed by AI Agent Rank editors · Last verified 2026-05-23
Our take
The right course for the moment a 'just stuff it into the context window' RAG starts failing. Covers retrieval evaluation, sentence-window retrieval, auto-merging, and the production-failure modes that toy RAG demos don't surface. Free, taught by the LlamaIndex founder + the team behind TruLens evaluation. The pre-req: you should already have built a basic RAG and watched it answer questions wrong. If you haven't, start with a simpler intro.
Pros
- +Production-grade content — failure modes, not just happy paths
- +Free, 90 minutes, by LlamaIndex + TruEra principals
- +Evaluation is the under-covered topic in the RAG space
Cons
- −Assumes you already understand basic retrieval
- −LlamaIndex-flavored — if you're a LangChain shop, mental translation needed
Best for
- · Engineers whose basic RAG works in dev but fails in prod
- · AI engineers debugging hallucinations on retrieved context
Not ideal for
- · People building their first RAG — start simpler
- · Anyone allergic to LlamaIndex idioms
